with the curtain of air developed when the dis-
charge vanes are directed from 0º to 20º toward
the door opening.
If the air stream strikes any obstruction (the top
edge of the doorway, a door opening device, etc.),
the effectiveness of the air curtain will be greatly
reduced.
See Figure 1.
B. For optimum performance, the bottom of the air
curtain (discharge nozzle) should be no more than
1" above the top of the door opening with the air
curtain(s) mounted flush to the wall. If the air curtain
must be mounted higher, it must be spaced out from
the wall 3/8" for every inch the air curtain is above
the door opening. See Figure 3. For optimum
protection, any void between the air curtain and the
wall should be sealed along the full length of the air
curtain.
II. MOUNTING INSTRUCTIONS
(General)
INDOOR MOUNTING ONLY -
Environmental/Insect/Dust Control
The Architectural Low Profile 8 Air curtain is designed
to be an effective barrier against cold drafts in the winter
and hot air in the summer. To achieve optimum pro-
tection, the air curtain should be mounted on the inside
of the building, flush to the wall and as close to the top
of the door opening as possible. To ensure peak
performance, keep the air stream free of obstructions.
C. Electric heated air curtain(s) shall:
1. Have a minimum clearance of at least 1” between
    the sides and top of the air curtain and any
    combustible material.
2. Have a minimum clearance of at least 6’ between
    the bottom of the air curtain and the floor.
3. Be installed Indoors Only.
D. Proceed to either Section III - WALL
     MOUNTING or Section IV - SUSPENDED
     MOUNTING
The air curtain will not perform properly if negative
air pressure exists in the building. Under these
conditions, a means for makeup air to the building
must be provided so that the air pressure on both
sides of the opening is in balance.
Before mounting the air curtain, check the supporting
structure to verify that it has sufficient load-carrying
capacity to support the weight of the air curtain(s).
The mounting hardware (supplied by others) should
be capable of supporting a minimum of three (3) times
the weight of the air curtain.
See Table 1.
IMPORTANT: A minimum of 1” is required above
the top of the air curtain for the installation and removal
of the cover housing.

A. The Architectural Low Profile 8 Air curtain is
equipped with two ¼” threaded inserts on the back
of each air curtain (two per module on air curtains
84” and over). Insert and tighten the shoulder bolts
(provided in bag taped to the wall plate) into these
threaded inserts. A minimum of two shoulder bolts
are required; on air curtains comprised of modules,
use the outer threaded inserts and a minimum of
one of the inner threaded inserts.
B. Determine the exact mounting location of the air curtain.
NOTE: A minimum of 1” is required above
the wall mounting plate to provide clearance
for installation and removal of the air curtain.
FIGURE 3 - High Wall Mounting
F. Mark the wall in the centers of the ¼” holes drilled
     on the mounting plate.
C. Remove the wall mounting plate from the unit to install.
The wall mounting plate (included) is designed to fit
flush with the top of the Architectural Low Profile 8
Air curtain. Therefore the location of the wall mounting
plate will determine the final location of the top of the
air curtain.
G. Attach the mounting plate to the wall (hardware
     by others).

remove the wiring tray cover that is located closest
to the electrical rating nameplate. Remove the re-
quired knockouts and attach the necessary electrical
hardware. Save the wiring diagram found inside of
the wiring tray. See Figure 7.
D. For Standard Flush Wall Mounting, position the center
of the wall mounting plate over the center of the door
opening with the larger opening of the key hole slots
facing up. The wall mounting plate thickness provides
a natural ¾” space which allows for mounting it up to
4” above the opening. For optimum performance, the
bottom of the mounting plate should be no more than
2” or less than 1” above the top of the door opening.
See Figure 2. I. There are two sets of keyhole slots on the wall
High Wall Mounting must be used if the wall mounting
plate must be mounted higher than 4" above the door
opening: the mounting plate must be spaced out from
the wall 3/8" for every additional inch (over 4") that
the air curtain is above the door opening (clearance
height). See Figure 3. For optimum protection, do not
exceed the recommended maximum mounting height
of 8' above the finished floor. Any void between the
mounting plate and the wall should be sealed along
the full length of the mounting plate.		 mounting plate. In low overhead installations, the air
curtain may be staged in the lower keyholes to provide
clearance for electrical wiring and then moved to the
higher key holes after completion. Raise the air curtain
with the discharge opening facing down toward the
floor. While holding the air curtain level, slide the heads
of the shoulder bolts into the larger hole of the keyhole
slots of the mounting plate. Lower the air curtain into
place, keeping both ends level, allowing it to rest flush
with the mounting plate. See Figure 4.
E. Determine which of the four holes provided in each J. After attaching the air curtain to the mounting plate,
of the steel brackets of the wall mounting plate are
located where suitable support is available for the air
curtain. A minimum of one inside hole and one outside
hole from each bracket must be used for proper
support. Drill out the aluminum backing of the holes
chosen with a ¼” drill bit. If the provided holes on the
mounting plate are not located where suitable support
is available, drill new holes in the space provided on
the steel mounting brackets.		 ensure that the air curtain is seated and flush with the
mounting plate on all four sides.
K. Proceed to Section V - Electrical Connections.
IV. SUSPENDED MOUNTING
(Ceiling Suspension)
A. When the air curtain is top mounted, the wall mounting
plate is designed to store on the back of the air
curtain for future use. See Figure 5.
B. Four (4) factory installed ¼” threaded inserts are
located on the top of the air curtain for top suspension
mounting; on air curtains comprised of modules use
the outer threaded inserts.
To eliminate the slight deflection of longer air curtains,
the inner threaded inserts may also be used.
See Figure 6.
C. Determine the exact mounting location of the
     air curtain.
D. The top of the air curtain is provided with two knock-
outs on each side allowing for a left or right hand
power connection. Remove the wiring tray cover;
